ATTOR NEY Patented June 16, 1936 UNITED STATES PATENT OFFICE TABULATING MACHINE poration of Delaware Application May 19, 1931, Serial No. 538,429 In Germany March 21, 1931 28 Claims.

This invention relates to tabulating machines; that is to say to those statistical and accounting machines which operate on previously punched cards and either print the data indicated on said cards or accumulate such data, or both. In the illustrative instance of the invention shown in the drawings and hereinafter described in detail, said invention is embodied in that portion of a Powers tabulator which is sometimes called the 1:) base section of the machine and one of the objects of the invention may be said to be to provide an improved base section for the Powers tabulator. Many of the improvements, however, are of much wider application that that.

One object of the invention is to provide a tabulator that can be successfully operated at a considerably higher speed than has been practicable with the Powers tabulator. Another is to minimize the possibility of delay sometimes experienced with the present forms of tabulating machines owing to slight imperfections in the record cards. Another object is to provide improved and simplified mechanism for automatically recording group totals. This is done in the present machine under the control of the same sensing mechanism that governs the ordinary tabulating operations of the machine. The parts which control the machine when taking totals are positively actuated by the operating mechanism of the machine. Another object is to provide improved means whereby, at will, the machine may be converted so as to permit the use of space and total cards to control the recording of totals wherever such a mode of operation is desirable. Another object is to provide means whereby when the last card has been fed from the magazine a total will not automatically be taken so that if more cards are to be put into the magazine of the same group as before, a split total will not result from the exhaustion of the cards in the magazine. The invention includes means operating in an improved manner for locking the selection registering mechanism and important improvements in operation are associated with this 45 locking mechanism.

5 provide for the use of a simple form of stop card.

Another is to provide improved starting and stopping mechanism from a single control. Another object is to provide an improved drive mechanism of light running construction.

Further objects of the invention will be made apparent in the course of the specification.

To the above ends the invention consists in certain features of construction and combination and arrangement of parts, all of which will be fully set forth herein, and particularly pointed out in the claims. I

The machine, as a whole, is shown in Fig. 1 as comprising three principal sections, namely, the head I, the connecting section 2, and the base 3. The frame of the head i comprises a base plate 4 and said head is, or may be, of the usual Powers construction, an early form of which is shown in the patents to Powers Nos. 1,245,502 and 1,245,504, but modifications of which are shown in subsequent patents all of which, as well as the commercial machine itself, are well known in the art. The printing mechanism includes the type sectors 5 and the adding mechanism includes the gear sectors 6 which are controlled by the usual stops 1. 8 is the usual main shaft and I 0 the usual total shaft having the arm I I operated to set the machine for total taking by a link I2, all as described in the patent to LaskerNo. 1,376,555, dated May 3, 1921.

The base 4 of the head rests on side brackets I3 which are rigidly connected together by frame rods I4. These brackets I3 rest in turn on two main frame pieces, namely, aleft-hand frame member I5 and a right-hand frame member l6 (Fig. 2). The card hopper I! is at the front of the machine where it is convenient for the operator. It is supported by the frames l5 and I6 and the picker I8 is operated through a link 20 and arm 2| by a rock shaft 22.

The left-hand frame member I5 is made in the form of a sort of rectangular box, the walls of which are used for the support of the mechanism, but which box is normally closed toward the left by a cover plate 23 (Fig. 3) which cover plate is secured in position by screws. The righthand frame member I5 is in a somewhat similar form though thinner and it-is closed when the machine is in use bya cover plate 24 (Fig. 3). In this way most of the driving mechanism of the 5 machine is covered up-and protected when in use, but is readily accessible by removing the cover plates.

The main driving shaft 25 of the machine extends into both-frame members l5 and 46 where 10 it is journaled on ball bearings 26 which together with certain other ball bearings are held in place by plates 21 suitably shaped and perforated and screwed to the inner faces of the two frame members l5 and l6. 15

. In order to drive the shaft 25 it has mounted thereon a worm wheel 26 meshing with a worm 50 on a shaft 3| (Figs. 3 and 6) journaled by ball bearings in suitable brackets in the frame member l6 and having loosely mounted thereon a pulley 32 controlled by a clutch 35 which may be of the frlction disc type. This clutch is held in its working or closed position by a compression spring 34 acting on a collar 35 of the clutch member, whichcollar is controlled by a forked 25 am 36 fastened to a transverse rock shaft 31 and having studs entering a peripheral groove in the collar. The shaft 3| can be turned by a hand wheel 36 whose shaft 40 is slidabie in and out in a bracket 4| secured to the frame l6, said shaft having a toothed collar 42 which when the wheel is pushed in engages a toothed hub on the shaft as shown in Fig. 6. When the wheel is pulled out this connection is broken.

The pulley 22 is continuously driven by a belt 35 43 connected to a suitable electric motor in the lower part (not shown) of the machine, which motor is controlled by a switch 44 (Fig. 5).

When the motor is running the machine will be driven as long as the clutch 33 is in action. 40 The shaft 31, which controls this clutch, extends through the machine into the frame box l5 where it has a horizontal arm 45 which is connected by a vertical link 46, with a lever 41 mounted on top of the frame box l5 as shown 45 in Figs. 5 and 15-18. The parts are shown in Fig. 5 in their operating position with the machine running. In order to stop the machine link 46 is forced downward rocking the arm 36 against the tension of the spring 35 and releas- 50 mg the clutch. When this is done the clutch is locked in disconnect position by a pawl 46 pivoted to the wall of the frame l5 which pawl catches over a lug 50 projecting from the side of the link 46, the pawl being controlled by a spring 5|. The parts are shown in disconnect position in Figs. 17 and 18.

It is desirable that the machine always be stopped in the same position, namely, that in which the picker is in its extreme retracted position ready to feed a card into the machine. To this end the clutch is not released directly by hand but is released by a circular cam 52 mounted on the drive shaft 25 and having a projection 53 which operates a follower roller 54 on a lever 55 55 pivoted at 56 to the frame member 15, and said lever acting when operated to push upward a link 51 which, atits upper end, is guided, together with several other links, in a sheet metal plate 58 secured to the upper surface of the boxlike frame member l5.

For purposes of adjustment the lever which operates the link 46 is made in two pieces, both pivoted at 60. The lever 41 is one of these pieces and the other is a lever 6| of the first order hav- 76
